How to Install Trim on Rounded Corners


Installing trim around rounded corners is much less complicated than it seems, thanks to factory-made corner blocks. Instead of manipulating flat pieces of trim to cap a rounded corner, place a rounded corner cap as a transition between the flat trim on the adjoining walls. Corner blocks are available in many standard styles of baseboard trim. If you can't find a rounded corner block that matches the grooves on your trim, use a corner block with no grooves that is thicker than the rest of your trim. It will stand out, creating an attractive contrast.

Things You'll Need

  • Flat trim
  • Construction adhesive
  • Yellow glue
  • Hammer
  • Trim nails
  • Spread construction adhesive on the back of your corner piece and place it in the corner.

  • Apply yellow glue to the ends of the trim that will butt against the sides of the rounded corner trim.

  • Place the trim next to the rounded corner piece and reposition the corner block if necessary.

  • Nail the flat trim in place, using a hammer and trim nails. The corner piece doesn't need to be nailed.
